The rlpr package makes it possible (or at the very least, easier) to print files on remote sites to your local printer. It includes BSD-compatible replacements for `lpr', `lpq', and `lprm', whose functionality is a superset of their BSD counterparts. In other words, with the rlpr package, you can do everything you could do with the BSD printing commands, and more. The programs are all smaller, cleaner, and more portable than their BSD equivalents, and supported on just about any POSIX.1 system.

romfser is userland program for listing,
extracting, and partially mangling romfs images.
You can provide it with an offset in an image
where the file system starts. The mangling ability
is expressed in file substitution, where the new
file has to be equal or smaller in size compared
to the file being replaced. It can extract single
files into the current directory or extract the
whole filesystem while preserving the directory
structure.

rospell is a UTF-8 text editor for programmers and
general use. It features syntax highlighting, a
code beautifier for C and C++, and support for
gdb, ctags, grep, diff, and merge. It includes
spellers for English, French, German, Spanish, and Romanian languages. Romanian aspell and hunspell dictionaries are also available.

rr is a basic command-line utility designed to
retain/recall file and directory paths. This is
done by treating the filename itself as a unique
key to be referenced for future rr program calls.
The purpose of this is to assist the user in
shorthand typing and/or not having to remember
arbitrary full paths. So, for example,
"/etc/httpd/conf/httpd.conf" can be referenced as
"// httpd.conf" in daily operations.

rsaver is a simple X screensaver that only uses
Xlib. After a specified amount of time it will
start to draw radioactive signs. If a timeout is
not specified, the timeout value is obtained from
the X server.

rsget.pl is an application designed to retrieve files from download services (like RapidShare, MegaUpload, and many more). It has a long list of features already implemented, and an even longer TODO list.

rsyncbackup is a handy tool for scheduled backups
using rsync. rsyncbackup lets you easily setup
multiple source folders and destinations, both
locally, on your iPod or external firewire disk,
or at a remote destination using ssh. rsyncbackup
has no GUI, but is based on editing configuration
files. The script is meant to be run in a crontab,
so user interaction is not neccesary. Basic
terminal skills are required to use the program.
